128GB DDR5 ECC RDIMM kit for Dell PowerEdge R760xa

This registered server memory kit delivers 128GB across eight 16GB modules built for the Dell PowerEdge R760xa. ECC and registered operation protect data integrity in mission-critical workloads. The kit targets IT teams upgrading compatible Dell rack servers.

Capacity and headroom at 4800MT/s CL40

Eight single-rank 1Rx8 modules run at DDR5 4800 (PC5-38400) with CL40 latency and 1.10V voltage. The 128GB total suits virtualization, databases and large datasets. Workloads exceeding this capacity or demanding higher speeds will need additional DIMM slots or faster modules.

288-pin registered design without heat spreaders

Modules use major OEM chips from Samsung, Micron or Hynix on a 288-pin RDIMM form factor. No heat spreaders are fitted, so airflow in the server chassis handles cooling. Registered buffering reduces electrical load on the memory controller for stable operation in dense configurations.

Questions about this item

Will this 128GB DDR5 4800 kit work alongside existing RDIMMs already installed in a PowerEdge R760xa?

The modules are registered ECC DDR5 4800 CL40 1.10V 1Rx8 parts; they must match the speed, voltage, rank and ECC type of any DIMMs already present, so check the server's current configuration before mixing.

How can I verify the kit is running at 4800 MT/s with ECC active after installation?

Open the system BIOS or iDRAC interface and confirm the reported memory speed is 4800 MT/s, CAS latency 40 and ECC status shows enabled.

What ships in the box and do I need any extra brackets or cables?

The package contains eight 16GB 288-pin DDR5 RDIMM modules; no heat spreaders, brackets, cables or additional hardware are included.
